For English beginners, it is difficult to use tense correctly.

Before I left for school, one of the staff members had called me and said that (I had to attend the meeting after all the classes finished.)

I'm not sure whether I use tense in a correct way or not. Please point out and revise if there is any mistake.( I think there are)

I know that the number of people whose mother tongue is Spanish is much higher than that of portuguese. However, I heard before that If I can speak Portuguese, I can understand more or less Spanish, but I can't understand Portuguese even if I am fluent in Spanish. In terms of many factors, which is the more useful do you think?

I have a question about English sentences, are these correct?

I don't know how I should say this in English

I don't know what I should say this in English

I am getting used to speaking English

I have got(ten) used to speaking English

Which is natural expression for native speakers?

I want to practice speaking English! If possible, I want to talk with you in English by Skype. I speak Japanese and if you want, I can teach you Japanese. Could you help me?

Now, I am studying English and I have one question about 'shall'.

Until now, I have used 'will' in almost all the sentences I've written instead of 'shall'. When I looked up the word 'shall' in my dictionary, it said that 'shall' is almost the same as 'will', but 'shall' is mainly used in U.K. rather than in U.S.. As was written in the dictionary, does 'shall' have the same meaning as 'will' and can I use 'shall' instead of 'will' .

I think it is important to decrease the number of incidents happening in this society to zero.

Can this expression 'decrease to zero' be correct?

I moved to this country.

I have moved to this country.

What differs in meaning if I say first sentence instead of second one?

I heard before that these three languages derive from the same language, latin. Therefore, these languages have a lot of characteristics in common. If a native Spanish speaker talks with people whose mother tongue is portuguese or italian, will any troubles happen in terms of language? And if I start to study one of these languages, will it be easier for me to master the other two languages because of similarities?

I'm studying English and have a great difficulty using correct words. For example, when someone is punctual and never (or rarely) late for school or office and miss trains,

1.He is careful about the time

2.He is careful about time

Which is correct sentence? I heard when you ask someone present time, you say 'do you have the time?'. So I wonder 1st sentence is better, but I am not sure. If neither is correct, what do native English speakers say?

1 I'm sorry to be late in handing in this homework.

2 I'm sorry for being late in handing in this homework.

3 I'm sorry for delay in handing in this homework.

If none of these is natural for native speakers, please tell me what they say in this kind of situation.

Have you ever played a game called the elder scrolls 4 'oblivion'? I want to travel in a country whose atmosphere is similar to this game, full of nature such as forests mountains lakes etc. Which country is suited for this condition the most?

I heard even German people can't understand what Swiss say because of the difference of pronunciation or word spell (or grammar?) etc. When people go to Switzerland and communicate by using German, can't I make myself understood by using German spoken in Germany? If so, how should I study?

I want to travel in U.K and France this year. I want to eat delicious food in both countries. If possible, I want to see beautiful natural landscape too, including lakes, mountains, forests, hills etc. Are there any recommended places I should visit? Are both countries full of beautiful nature compared with other countries in Europe.

Whatever the gestures used, you will find that there are some hints which only words can hardly show.

In this sentence, what does 'Whatever the gestures used' mean?

A short time ago, I asked similar question, but please teach me one more about English grammar.

Last time, I asked about the difference between past tense and present perfect in this sentence,

She may not be able to walk freely for a while, because she has just left a hospital.

Then, if I change this sentence into this, how does the meaning change?

She will not be able to walk unaided for a while, because she will have just left a hospital.

How about this sentence? I want to mean something like this situation,For example, a boy is now in a house of his mother's friend because his mother is in a hospital because of sickness, and he will go home tomorrow because his mother can leave a hospital, then the previous day, the mother's friend says this to him.

I'm sorry if you can't understand well my question because of my broken English.

She may not be able to walk freely for a while, because she has just left a hospital.

If I use only 'left' instead of using present perfect, does the meaning of this sentence change?

A goal keeper jumped to the opposite side of the goal to which he kicked the ball.

I can't use the word 'opposite' freely yet. Can this be understood even if this is not grammatically correct. To make this correct sentence, hou should I revise?

You have to study much harder than you (did/ have done) until now.

Which is better in terms of grammar?

I want to use this expression in my address.

This year is almost over.

Can you say you have had a good year?

I am not sure about the difference between past tense and present perfect. In this case, should I use 'you had a good year' instead?
